* mac80211: add key flag for management keysJohannes Berg2012-09-101-0/+32
| | | | | | | | | | | | Mark keys that might be used to receive management frames so drivers can fall back on software crypto for them if they don't support hardware offload. As the new flag is only set correctly for RX keys and the existing IEEE80211_KEY_FLAG_SW_MGMT flag can only affect TX, also rename the latter to IEEE80211_KEY_FLAG_SW_MGMT_TX.

* | mac80211: fix current vs. operating channel in preq/beaconJohannes Berg2012-07-311-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | When sending probe requests, e.g. during software scanning, these will go out on the *current* channel, so their IEs need to be built from the current channel. At other times, e.g. for beacons or probe request templates, the IEs will be used on the *operating* channel and using the current channel instead might result in errors. Add the appropriate parameters to respect the difference. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* | mac80211: add PS flag to bss_confEliad Peller2012-07-311-2/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ps mode is indicated per device (rather than per interface), which doesn't make a lot of sense. Moreover, there are subtle bugs caused by the inability to indicate ps change along with other changes (e.g. when the AP deauth us, we'd like to indicate CHANGED_PS | CHANGED_ASSOC, as changing PS before notifying about disassociation will result in null-packets being sent (if IEEE80211_HW_SUPPORTS_DYNAMIC_PS) while the sta is already disconnected.) Keep the current per-device notifications, and add parallel per-vif notifications. In order to keep it simple, the per-device ps and the per-vif ps are orthogonal - the per-vif ps configuration is determined only by the user configuration (enable/disable) and the connection state, and is not affected by other vifs state and (temporary) dynamic_ps/offchannel operations (unlike per-device ps).

| | | | | | | | | | | | | | | | | | When AP interface is going down, the stations are flushed (in ieee80211_do_stop()) only after the beaconing was stopped. However, drivers might rely on stations being removed before the beaconing was stopped, in order to clean up properly. Fix it by flushing the stations on ap stop.

This fixes a number of small issues with the ROC implementation: * offloaded remain-on-channel couldn't be queued, now we can queue it as well, if needed * in iwlwifi (the only user) offloaded ROC is mutually exclusive with scanning, use the new queue to handle that case -- I expect that it will later depend on a HW flag The bigger issue though is that there's a bad bug in the current implementation: if we get a mgmt TX request while HW roc is active, and this new request has a wait time, we actually schedule a software ROC instead since we can't guarantee the existing offloaded ROC will still be that long. To fix this, the queuing mechanism was needed. The queuing mechanism for offloaded ROC isn't yet optimal, ideally we should add API to have the HW extend the ROC if needed. We could add that later but for now use a software implementation. Overall, this unifies the behaviour between the offloaded and software-implemented case as much as possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IDLE handling in HW off-channel is broken right now since we turn off IDLE only when the off-channel period already started. Therefore, all drivers that use it today (only iwlwifi!) must support off-channel while idle, so playing with idle isn't needed at all. Off-channel in general, since it's no longer used for authentication/association, shouldn't affect PS, so also remove that logic. Also document a small caveat for reporting TX status from off-channel frames in HW remain-on-channel. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* | cfg80211: clarify set_channel APIsJohannes Berg2012-06-061-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we've removed all uses of the set_channel API except for the monitor channel and in libertas, clarify this. Split the libertas mesh use into a new libertas_set_mesh_channel() operation, just to keep backward compatibility, and rename the normal set_channel() to set_monitor_channel(). Also describe the desired set_monitor_channel() semantics more clearly. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | cfg80211: provide channel to join_mesh functionJohannes Berg2012-06-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just like the AP mode patch, instead of setting the channel and then joining the mesh network, provide the channel to join the network on to the join_mesh() function. Like in AP mode, you can also give the channel to the join-mesh nl80211 command now. Unlike AP mode, it picks a default channel if none was given. As libertas uses mesh mode interfaces but has no join_mesh callback and we can't simply break it, keep some compatibility code for that case and configure the channel directly for it. In the non-libertas case, where we store the channel until join, allow setting it while the interface is down. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* | cfg80211: provide channel to start_ap functionJohannes Berg2012-06-051-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of setting the channel first and then starting the AP, let cfg80211 store the channel and provide it as one of the AP settings. This means that now you have to set the channel before you can start an AP interface, but since hostapd/wpa_supplicant always do that we're OK with this change. Alternatively, it's now possible to give the channel as an attribute to the start-ap nl80211 command, overriding any preset channel.

* | mac80211: clean up ieee80211_set_channelJohannes Berg2012-06-051-16/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no need for ieee80211_set_channel to check whether a change in configuration happened since ieee80211_hw_config() auto-detects it. Additionally, it's wrong to pretend the HT config for the BSS changed, it didn't, the BSS can't be up & running (AP beaconing etc.) when the channel type is changed anyway.
